Seismic activity at La Soufrière, St Vincent, has remained low since the tremor associated with the explosion and ash venting on 22 April.
In the last 24 hours, only a few long-period and volcano-tectonic earthquakes have been recorded.
In a bulletin issued on Saturday, the UWI Seismic Research Centre said persistent steaming could be seen from the observatory once the cloud cover is high enough.
Thermal anomalies, which indicate high temperatures inside the new crater, continue to be detected by the NASA FIRMS alert system.
Measurements of the sulphur dioxide (SO2) flux were done yesterday (20 May) and yielded an average SO2 flux of 461 tons per day.
SO2 flux is an indicator that fresh magma from a deeper source is being degassed.
The volcano continues to be in a state of unrest but an escalation in activity can still take place with little or no warning.
The volcano is at alert level ORANGE.
